Does anyone fancy weighing in on a disagreement we're having regarding object-orientation and encapsulation?

If you have a class - let's say it's a Policy class, for example - that holds all of its relevant properties, where would you expect to find the process that saves any edited properties back to the underlying database? Would you expect the class to have its own Save method, or would you expect the Save method to be in a completely separate servicing layer that accepts your Policy instance as a parameter and then saves it?
